It is important to choose the right reduction ratio to maximize efficiency based on your required flight performance.
The Goblin has many possible reduction ratios at your disposal. It is possible to optimize any motor and battery combination.
It is recommended to use wiring and connectors appropriate for the currents generated in a helicopter of this class.
Below is a list of available reduction ratios:
H0015-16-S - 16T Pinion = ratio 13.4:1
H0015-18-S - 18T Pinion = ratio 11.9:1
H0015-19-S - 19T Pinion = ratio 11.3:1
H0015-20-S - 20T Pinion = ratio 10.7:1
H0015-21-S - 21T Pinion = ratio 10.2:1
H0015-22-S - 22T Pinion = ratio 9.7:1
H0015-23-S - 23T Pinion = ratio 9.3:1
H0015-24-S - 24T Pinion = ratio 8.9:1
H0015-26-S - 26T Pinion = ratio 8.2:1
Some example configurations:
Note: Although the Goblin can fly at high rpm, for safety reasons we suggest to not exceed 2200 rpm.
